Newbie - Megane Audio

Hi there

I recently bought a 2001 Megane with no stereo in it, and being a novice I seem to have purchased an "Update List" stereo rather than a "Tuner List". Is this a major issue? There is no display and every time I press a button I get a loud beeping sound. There is definately power because the clock lights up and the cd ejects.

Will I need to sell it on and get a Tuner List or is there something I can do to make it work? I don't have a cd changer with it. If there is something I can do can someone explain simply how it is done, so that I might understand!
